Disclosed is a method to make actuator moving (seek operation) sounds lower in a Hard Disk Drive (HDD). That is realized by changing the duty of the seek operations. And the duty must be selectable by a user who demands a silent HDD for comfortable surroundings. Sounds comes mainly from the seeking operation. Then reducing the duty of the operation makes the noise level lower and also the performance lower. But it is difficult to tell the proper noise level. It depends on the user and the environment.
